We're at the point of the NFL season when the combination of injuries and uninspired play results in a ton of tinkering at the league's most important position.

Several shifts were revealed Wednesday.

The rundown:

In Cleveland, Jason Campbell is in and Brandon Weeden is out after Weeden struggled the past couple of games. So, business as usual for the Browns then, since the franchise has now turned to 20 different starters since 1999. With the trade of Trent Richardson, it has been a long year for long-suffering Browns fans. Few expect Campbell to brighten things up.

Meanwhile, the similarly dismal Vikings are going back to the guy they decided wasn't the answer -- Christian Ponder -- because newcomer Josh Freeman is being tested for a possible concussion suffered Monday against the New York Giants. Freeman was horrendous in the contest.
